Functions

NRF_STATIC_INLINE void nrf_usbreg_event_clear(NRF_USBREG_Type *p_reg, nrf_usbreg_event_t event)

Function for clearing the specified USBREG event.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • event – [in] Event to be cleared.

NRF_STATIC_INLINE bool nrf_usbreg_event_check(NRF_USBREG_Type const *p_reg, nrf_usbreg_event_t event)

Function for retrieving the state of the USBREG event.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • event – [in] Event to be checked.

Return values:

  • true – The event has been generated.

  • false – The event has not been generated.

NRF_STATIC_INLINE void nrf_usbreg_int_enable(NRF_USBREG_Type *p_reg, uint32_t mask)

Function for enabling specified interrupts.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • mask – [in] Mask of interrupts to be enabled.

NRF_STATIC_INLINE void nrf_usbreg_int_disable(NRF_USBREG_Type *p_reg, uint32_t mask)

Function for disabling specified interrupts.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • mask – [in] Mask of interrupts to be disabled.

NRF_STATIC_INLINE uint32_t nrf_usbreg_int_enable_check(NRF_USBREG_Type const *p_reg, uint32_t mask)

Function for checking if the specified interrupts are enabled.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

  • mask – [in] Mask of interrupts to be checked.

Returns:

Mask of enabled interrupts.

NRF_STATIC_INLINE uint32_t nrf_usbreg_status_get(NRF_USBREG_Type const *p_reg)

Function for getting the whole USBREGSTATUS register.

Parameters:

  • p_reg – [in] Pointer to the structure of registers of the peripheral.

Returns:

The USBREGSTATUS register value. Use nrf_usbreg_status_mask_t values for bit masking.
